B (Bulb)- At the B setting, the shutter remains open as long as the shutter release button remains fully depressed.

Bracketing

- Take a series of pictures at different exposures.

Burning- Providing extra exposure to an area of the print to make it darker, while blocking light from the rest of the print.

Depth of Field

- The range of acceptably sharp focus in front of and behind the distance the lens is focused on.

Dodging

- Blocking a portion of the light when printing a photograph so that an area of the image will be made lighter.

Element

- One piece of glass comprising the internal optics of a lens.

Exposure

- Light striking a sensitized material (film or paper emulsion).

Fisheye

- An ultra-wide angle lens which purposely introduces barrel distortion so straight lines near the edges of the frame appear to curve out.

Flare

- Image degradation caused by stray light which passes through the lens but is not focused to form the primary image. Often caused by light bouncing off internal air-toglass surfaces.

Focal Length

- The distance from the optical center of a lens to the image plane when the lens is focused to infinity.

ISO

- International Standards Organization; the number represents the film's sensitivity to light. A higher ISO number indicates the film is more sensitive and requires less light for a proper exposure.

Photography

- From the Greek the means "painting or writing with light."

Shutter Speed

- How fast the camera's shutters open. Determines how long the film is exposed for.

Shutter Priority

- When the photographer selects the shutter speed and the camera automatically sets the corresponding aperture.

SLR

- Single Lens Reflex; a camera with one lens (as opposed to Twin Lens Reflex like the Rolleiflex) that involves a mirror and prism that the viewer looks through (as opposed to a point and shoot or rangefinder where the viewer looks through a separate viewfinder.

Sunny-16 Rule-

A guideline that states that you can expose a normal scene, lit by bright sunlight, at an aperture of f16 and a shutter speed equivalent to the film speed (ISO or

ASA) being used.

TTL

- Through-the-lens; commonly used when referring to metering through the lens as opposed to via a separate meter.
